Hello Monks!

One of my daily running applications (6am) needs the yesterdays date, or better the date of $param-1day.

Yesterday, sunday, was here in germany the change from 2am to 3am. Running on sunday with date=20100328 it was correct yday=20100327. But I got today with date=20100329 yday=20100327 again.

Code for this:

#!/bin/perl
use strict;
use Time::Local;

die "Wrong parameter count." unless scalar(@ARGV) == 1;
die "Wrong parameter format." unless $ARGV[0] =~ /(\d{4})(\d{2})(\d{2}
+)/;

my @d = localtime(timelocal(0, 0, 0, $3, $2-1, $1) - 86400);
printf("%04d%02d%02d", ($d[5]+1900), $d[4]+1, $d[3]);

My question is now how I can fix this issue?

I searched for another module wich help me on this, but Date::Manip have the same problems (reported in "Known Bugs") and Date::Calc have to much dependencies that I have to install, just for task.

Greetings, Schaelle
